Creating two lines of concrete piles close to a building to enable safe foundations for a new construction, right on the lake front in Wanaka.
Using our new multishank rotopercussion unit , we have drilled 80 holes 1.20 meters deep and used thick grouts as a flushing medium.
Drill on Wanaka Lake front
Access: Even with a fragile barrier at the top of the slope, we are still able to find a way to rig safely.
Drillability: The presence of clay at different depths has obliged us to alternate the use of a down hole hammer and drag bits, to drill top anchors 4m deep embedded in 90mm holes, whereas on most jobs of that kind just a hand-drill and 2m holes should do.
